The ATTIME suspend function will be executed for the target consistency group only when all the copy pairs in the
consistency group are in the DUPLEX status.

Legend:

pairs

SER: SUSPER

DUP: DUPLEX

NOTE:

Even if

Table 101 (page 309)

shows that the commands with SELECT(COND) specified

are subject to processing for the copy pair statuses, you might not be able to execute such commands
depending on the hardware status and copy type. For example, for both BC Z and Cnt Ac-S Z,
when the copy group contains a copy pair with the status of PENDING and the YKSUSPND command
is executed for copy groups with no consistency group ID specified, an error might occur.

Batch Processing for Multiple Copy Pairs

Copy pair operations are performed by volume, or collectively for multiple copy pairs (batch
processing), depending on the combinations of commands and parameters. When batch processing
is performed, if there is at least one copy pair subject to processing in the processing unit, the copy
pairs in the processing unit are subject to processing. However, processing is performed by volume
if the DEVN, VOLUNIT, or ERRCHK parameter is specified.
